[Pneumocystis pneumonia in patients with Hodgkin lymphoma].

Aim: To assess the results of diagnosing and treating Pneumocystis pneumonia (PP) in patients with Hodgkin lymphoma (HL) over 15 years.

Subjects And Methods: In 1999 to 2013, PP occurred in 22 (3%) of 741 HL patients receiving programmed polychemotherapy (PCT). The male/female ratio was 1:1.1; median age was 32 (18-65) years. Advanced stages (IIB-IV) of the disease were seen in 82% of the patients. The diagnosis of PP was established when Pneumocystis (more than 5 cysts in the specimen) was detected in the lavage fluid by indirect immunofluorescence assay.

Results: PP developed after 4 or more cycles of PCT. Along with Pneumocystis, all the cases were found to have additional pathogens: herpes virus in 72% and bacteria and fungi in 33%. All the patients received combined antimicrobial therapy using high doses of intravenous trimethoprim-sulfamethoxazole. Ten (45%) patients required mechanical ventilation (MV). The total mortality in PP was 32% (7 patients died); moreover, none of the patients without MV died whereas the mortality among those who had MV was 70% (7 of the 10 patients died). High death rates (80%) were noted among the patients with recurrent and resistant HL.

Conclusion: PP should be prevented with trimethoprim-sulfamethoxazole in patients with LH during PCT. If respiratory failure and X-ray signs of interstitial pneumonia appear, there is a need for fibrobronchoscopy with bronchoalveolar lavage and comprehensive microbiological testing of lavage fluid.
